Abstract

LA INVENCION SE REFIERE A UNA LAMPARA DE VAPOR DE SODIO A ALTA PRESION QUE TIENE UN RECIPIENTE DE DESCARGA (3) CON UNA PARED DE CERAMICA (3A) DE OXIDO DE ALUMINIO EN EL QUE HAY POR LO MENOS NA COMO COMPONENTE DE RELLENO IONIZABLE, UN GAS RARO Y AL (20). SEGUN LA INVENCION, EL AL SE COLOCA CERCA DE LA PARED DEL RECIPIENTE DE DESCARGA EN UN LUGAR EN QUE ALCANZA UNA TEMPERATURA DE POR LO MENOS 1000 K DURANTE EL FUNCIONAMIENTO DE LA LAMPARA.THE INVENTION IS RELATED TO A HIGH PRESSURE SODIUM VAPOR LAMP WHICH HAS A DISCHARGE CONTAINER (3) WITH A CERAMIC WALL (3A) OF ALUMINUM OXIDE IN WHICH THERE IS AT LEAST NA AS IONIZABLE FILLING COMPONENT, A RARE GAS AND AL (20). ACCORDING TO THE INVENTION, THE AL IS PLACED NEAR THE WALL OF THE DISCHARGE CONTAINER IN A PLACE WHICH REACHES A TEMPERATURE OF AT LEAST 1000 K DURING THE OPERATION OF THE LAMP.
